j. Final inspection.

3.5.5. Percent Complete. With each update, update the percent complete for each activity started, based on the realistic assessment of earned value. Activities which are complete but for remaining minor punch list work and which do not restrain the initiation of successor activities may be declared 100 percent complete. To allow for proper schedule management, cost load the correction of punch list from government pre-final inspection activity(ies) not less than 1% of the total contract value which activity(ies) may be declared 100% complete upon completion and correction of all punch list work identified during pre-final inspection(s).

3.5.6. Remaining Duration. Update the remaining duration for each activity based on the number of estimated work days it will take to complete the activity. Remaining duration may not mathematically correlate with percentage found under paragraph entitled Percent Complete.

3.5.7. Anticipated Adverse Weather. Reflect the number of anticipated adverse weather delays allocated to a weather sensitive activity in the activity's calendar.

a. The following schedule of monthly anticipated adverse weather delays is based on NOAA data and will constitute the baseline for anticipate adverse weather.

b. Time extensions may be granted under the DEFAULT contract clause if the weather at the site is more severe than the adverse weather anticipated for any given month and if the unusually severe weather can be shown to actually cause a delay to the completion of the project – that is cause impact/delay to activities on the critical path. The delay must be beyond the control and without fault or negligence of the contractor.

c. Monthly Anticipated Adverse Weather Delay Work Days Based on 5 Day

Work Week: Jan 22, Feb 20, Mar 14, Apr 0, May 0, Jun 0, Jul 4, Aug 3, Sep 4, Oct 1, Nov 20, Dec 22.
